Question 31

First step in urine formation

Answer 31

Filtration

Question 32

Urine reservoir

Answer 32

Bladder

Question 33

Tube from bladder to outside

Answer 33

Urethra

Question 34

reabsorption

Answer 34

moves salutes and waste out and filters it back into the bloodstream

Question 35

filteration

Answer 35

filters waste out of blood and into urine

Question 36

secretion

Answer 36

molecules and substances travel out of blood and body

Question 37

formation of urine pathway

Answer 37

1. bloodstream renal artery (or reabsorption (water sugar salts) to step 4) 2. glomerulus (water sugar salts urethra wastes) (filtration) 3. bowman's capsule 4. proximal convoluted tubule (secretion) 5. loop of henle 6. distal convoluted tubule component of urine (ureu, wastes, salts, water, acids) 7. collecting tubule 8. renal papillae 9. calyces 10. renal pelvis 11. ureter 12. urinary bladder 13. urethra 14. urinary meatus

Question 38

Explain the role of the hormones ADH and aldosterone in chemical control of urine secretion.

Answer 38

Maintains balance of body fluid thru reabsorption

Question 39

What causes an increase in ADH secretion?

Answer 39

an increase in osmotic blood pressure due to salt retention causes an increase in ADH secretion, dehydration, low blood volume, stress

Question 40

What causes the release of aldosterone?

Answer 40

adrenal cortex releases aldosterone/low bp or sodium lvls

Question 41

What do diuretics due to urinary output? How? Use an example.

Answer 41

diuretics increase urinary output. they do this by inhibiting the reabsorption of water. for example. alcohol inhibits the secretion of ADH which increases urinary output and may cause dehydration

Question 42

Describe how you would explain to a patient what healthy urine output and color is. What should they do if it is discolored?

Answer 42

Healthy urine output color is a pale yellow. if it is dark yellow, you need to drink more water. if it is clear, you need to drink less water. if it is discolored, visit a doctor. normal urine output is 6-8 times a day, 48-64 ounces, or 180L

Question 43

You have just ran a mile and sweated profusely. When you urinate, you notice there is only a small amount and it is concentrated. Explain what happened.

Answer 43

your body secreted waste products through sweating. therefore, there is not much urine or waste left in the body during urination
